Abstract
The invention discloses a rubber on-off key, and relates to the technical field of auto parts. The rubber on-off key comprises a rubber on-off key body, wherein the rubber on-off key body comprises a plurality of conducting columns and external rubber layers; each conducting column is coated with the corresponding external rubber layer; one end of each conducting column is sealed in the rubber on-off key body; the other end of each conducting column extends to an end opening in the rubber on-off key body, and is flush with the end opening; each external rubber layer is prepared from the following raw materials in part by weight: 25 parts of polyurethane rubber, 75 parts of butyl rubber, 6 parts of zinc oxide, 6 parts of dithiocar-bamate, 5 parts of a p-phenylenediamine anti-aging agent, 55 parts of nanometer pottery clay, 10 parts of paraffin and 13 parts of resin sulfide. Through the adoption of the rubber on-off key provided by the invention, the problems that the conventional processing of the rubber on-off key is complex, a metal film is liable to fall out, and the service life is short can be solved.
Description
Technical field
The present invention relates to technical field of automobile, especially a kind of elastomeric switch key.
Background technology
In the electric-control system of automobile, commonly use on & off switch to open and close, a kind of on & off switch includes the on & off switch body of a rubber, one deck conductive metal film is electroplated at the contact-making surface of on & off switch body and electric controller, this elastomeric switch key also exists processing technology complexity and metal film easily comes off, the problem that its useful life is short, therefore produces that a kind of production technology is simple and wear-resisting, long service life and low-cost elastomeric switch key is the problem that those skilled in the art need solution badly.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of elastomeric switch key, and this on & off switch can solve existing elastomeric switch key processing technology complexity and metal film easily comes off, the problem that useful life is short.
In order to solve the problem, technical scheme of the present invention is: this elastomeric switch key, include elastomeric switch key body, described elastomeric switch key body is made up of many conductive poles and the outer rubber layer that wraps up described many conductive poles, one end of described conductive pole is sealed in described elastomeric switch key body, the other end of described conductive pole extends the port of described elastomeric switch key body, and concordant with this port.
In technique scheme, scheme can also be more specifically: described conductive pole is metallic conduction post.
Further: described outer rubber layer adopts the raw material of following weight portion: polyurethane rubber: 25 parts; Butyl rubber: 75 parts; Zinc oxide: 6 parts; Dithiocar-bamate: 6 parts; P-phenylenediamine (PPD) age resistor: 5 parts; Nanoclay: 55 parts; Paraffin: 10 parts; Curing resin: 13 parts.
Owing to adopting technique scheme, the present invention has following beneficial effect:
1, because elastomeric switch key body is made up of many conductive poles and the outer rubber layer that wraps up described many conductive poles, its structure simple production technique simple and conductive pole difficult drop-off, long service life;
2, polyurethane rubber and butyl rubber is adopted to be main material because outer rubber layer have employed, the outer rubber layer synthesized is made not only to have good electrical insulating property, resistance to ozone, ageing-resistant, thermal endurance, and tool has good wearability, oil resistance and high strength, high resiliency.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Fig. 2 is the A-A place cutaway view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing embodiment, the invention will be further described:
Elastomeric switch key shown in Fig. 1, Fig. 2, include elastomeric switch key body, elastomeric switch key body is made up of the conductive pole 2 of many metals and the outer rubber layer 1 that wraps up many conductive poles 2, one end of conductive pole 2 is sealed in elastomeric switch key body 1, the other end of conductive pole 2 extends the port of elastomeric switch key body 1, and concordant with this port; Outer rubber layer 1 adopts the raw material of following weight portion: polyurethane rubber: 25 parts; Butyl rubber: 75 parts; Zinc oxide: 6 parts; Dithiocar-bamate: 6 parts; P-phenylenediamine (PPD) age resistor: 5 parts; Nanoclay: 55 parts; Paraffin: 10 parts; Curing resin: 13 parts.
Because elastomeric switch key body is made up of many conductive poles and the outer rubber layer that wraps up described many conductive poles, its structure simple production technique simple and conductive pole difficult drop-off, long service life; Polyurethane rubber and butyl rubber is adopted to be main material because outer rubber layer have employed, the outer rubber layer synthesized is made not only to have good electrical insulating property, resistance to ozone, ageing-resistant, thermal endurance, and tool has good wearability, oil resistance and high strength, high resiliency.
